Barcelona

In comparison to Madrid, the second-largest city in Spain provides a completely different travel experience. Its coastal location lends it a more resort-like atmosphere, complete with warm, sunny weather on most days of the year. It is located on the country's northeast coast, near the Mediterranean Sea, and appears to have a much more modern, progressive vibe than Madrid and other Spanish cities.

Barcelona's must-see tourist attractions include the city's massive Sagrada Familia modern cathedral and the Joan Miro museum, which was conceived by the iconic artist himself before his death. Other attractions in Barcelona include the city's nearly three miles of beaches and La Rambla, a massive, tree-lined, pedestrian-only street. It is recommended that you ride the funicular (incline railway) to the top of Tibidabo, a local mountain with a beautiful church and amusement park. In addition, you'll be rewarded with breathtaking views of the city and surrounding countryside.
